Two views from the Rainbow Falls overlook, downstream of the Wailuku River streamgage near Hilo, Hawaii. The image on the left shows a typical base flow of about 35 cubic feet per second (cfs). The image on the right shows the early impact of Hurricane Lane with a flow of about 26,000 cfs taken at 8:35 a.m. HST, August 23, 2018. This U.S.

Many of the earthquakes in Hawaii that extend offshore and up the island chain are due to plate bending, or flexure. The upper panel shows magnitude-5 and greater earthquakes since 1861, with some notable events labeled.

A sensor data logger recovered from the floor of Yellowstone Lake in the Deep Hole area in 2018 shows signs of melting due to unexpectedly high temperatures in sediments up to ~3 ft (1 m) away from an active hydrothermal vent. Image acquired by the Global Foundation for Ocean Exploration ROV Yogi on August 4, 2018.

Color bands in this radar interferogram depict the pattern of surface deformation at the Yellowstone caldera from September 22, 2004, to August 23, 2006. The southwest and northeast parts of the caldera floor rose about 11 cm (4.3 inches) and 15 cm (5.9 inches), respectively, while the north caldera rim near Norris Geyser Basin subsided about 7 cm (2.8 inches).

Pu‘u ‘Ō‘ō on May 3, 2018, as viewed from the helicopter overflight. The crater floor is collapsed, and a thin plume escapes from the gaping crater. The west flank cracked on April 30th around 2:30 pm HST, and minor amounts of lava oozed out of the crack (line of steaming features) just before the plumbing system catastrophically failed.

 Jenny White McKee and Pete Dal Ferro of the Pacific Coastal and Marine Science Center retrieve two airguns during the 2018 MATRIX cruise aboard the R/V Hugh R. Sharp.  The seismic streamer is visible on the winch in the foreground.

Four diesel-powered compressors chained to the deck of the R/V Hugh R. Sharp provided the air to power the seismic sources during the MATRIX cruise. 

Kīlauea Volcano's 2018 summit collapse, shown here on July 28 (left), and the lower East Rift Zone fissure 8 lava flow, shown here on July 2 (right), will be the focus of "Volcano Awareness Month" talks offered in January 2019.

USGS scientists continue to monitor some of the cracks in the lower East Rift Zone to check for any significant changes. This scientist is using an Infrared thermometer to record the temperature within the ground cracks.
